Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627444, here are decompositions:

53 + 31627391 = 31627444
71 + 31627373 = 31627444
197 + 31627247 = 31627444
227 + 31627217 = 31627444
293 + 31627151 = 31627444
311 + 31627133 = 31627444
353 + 31627091 = 31627444
467 + 31626977 = 31627444

Showing the first eight; more decompositions exist.
